hey, i got a login script up and running but I want to get it to display an error if the user inputs incorrect data - like right now, if they put in the wrong username/password it would redirect them back to the login page without displaying any errors, the validation page is separate from the actual form, and the form's action attribute sends the data to the validation script. The real question is how do i get the separate page to redirect back to the form and display what needs to be fixed?
Thanks ahead of time, |

ok thanks for the links - but I was wondering if there was a way to create a script that doesn't require any database software. I was thinking along the lines of a multiple if... elseif.... else..... statement.
Thank you,

| Ok well, the php script is to long to post here so just click on one of the links above and just copy and paste and make a new file when it says so and you'll have a login page up and going |

I have studied the matter yet re-starting from more basic PHP methods I have developed myself; browsing the web when interest into PHP password-ing comes on, it is hard to run into codes other than pretty-long, complex, database-tied, disheartening ones.
Play this on your Server; adjust filename.php in form action="" (in two places) according to the actual name you save the file.
Password is set by defining the $password variable at top code, final user can never detect it by inspecting source code; check it from browser's top-menù View => Page Source.
It works for one page at time so, if more protected pages are linked each others, user will have to re-enter password along their navigation.
| Code: |
<?php
$password = "hallo";
if (isset($_POST['enter'])){
if ($_POST['pass'] == $password){
echo('<h1>Reserved Content now displaying</h1>');
} else {
echo('wrong password entered - access denied<br>
<form action="filename.php" method="post">
<input name="pass" type="text"><input name="enter" value="enter page" type="submit">
</form>');
};
} else {
echo('submit your password:<br>
<form action="filename.php" method="post">
<input name="pass" type="text"><input name="enter" value="enter page" type="submit">
</form>');
};
?>
|
If interest arises with you, I'll be happy to be back with more explanation and better developed patterns.
Basically, here you have to replicate HTML content on three parts:
- the log-in form displaying at first download (there at bottom code);
- the log-in form again, coming on if user enters wrong/none password;
- the actual content of the password-protected page;
I am omitting html head body Tags for clarity.
This last two ones depending on the if (isset($_POST['submitter_name'])) statement.
Even though, PHP is able to collect value from that "pass"-named textbox directly, without such statement. So, this simpler code also works great and may result as better understendable; password is hello2U now, and the "wrong password ntered" case no longer is there:
| Code: |
<html>
<head><title>simplest php-passworded page</title>
</head>
<body bgcolor="#90C3FF">
<?php
if ($_POST['pass'] == "hallo2U"){
echo('<h1>Reserved Content now displaying</h1>');
} else {
echo('<div align="center"><br>
<form action="filename.php" method="post">
Password: <input name="pass" type="text"><input name="enter" value="enter" type="submit">
</form>
</div>');
};
?>
</body>
</html> |
If you wish password characters to be displaied as asterisks or bullets (it depends on which browser), change input type="text" into input type="password"
More different passwords to serve more users, also are possible!
Changing the if-statement row into something alike:
if ($_POST['pass'] == "hallo2U" || $_POST['pass'] == "wild" || $_POST['pass'] == "34y-99"){
allows to three different passwords. Here, || operator means "or" as in both PHP and JavaScript Languages.
What I would suggest to improve if so, is to convert the $_POST['pass'] into a more handy variable, to write the serie of allowed passwords this way:
| Code: |
$p = $_POST['pass'];
if (
$p == "hallo2U"
|| $p == "wild"
|| $p == "34y-99"
|| $p == "stray*code"
|| $p == "aGuy"
){ |
This works out sort of database existing along with the php file(s) there on the server. |
